Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684520, here are decompositions:
- 7 + 8684513 = 8684520
- 17 + 8684503 = 8684520
- 37 + 8684483 = 8684520
- 41 + 8684479 = 8684520
- 59 + 8684461 = 8684520
- 83 + 8684437 = 8684520
- 101 + 8684419 = 8684520
- 109 + 8684411 = 8684520
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,684,520 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
